How does Victoria's shield deals with Grappling/ Joint-locks?

On a theoretical fanfiction-like scenario, If someone with minor brute powers were to try grappling against her, putting her on a jointlock or putting her on a police hold ... how would that go?

A hold/jointlock is continous attack/preasure

Would her shield interpret the strong gripe capable of crushing bricks as a single attack and shatter allowing for the opponent to hold her?

But what after its recharge time ? Would it reform between her skin and the grip alloing her to fight back ? Or woudl it wait until the grip ended to reform?

Has she ever being put on a joint lock, submisions or choke on the story? ( only read until Ward's first few chapters).
